• Visual Basic Output line numbers progamatically (for logging/debug purposes) to a text file

  Using MS Visual Studio .Net 2003 VB I'm trying to figure out how to output the line number of a line of code that is executing.  This would be used for logging/debugging purposes. MS VC++ has the 'built in macro' by which this can be done __LINE__ and I have been unsuccessful in finding a VB equivalent - if one even exists. Best example I can give is in C++ because I have none for VB. void Example (int test) {    if (!test)       printf ("test not set @ line %d", __LINE__); } All that to say I need to know if there is an equivalent to __LINE__ in VB.  Thanks in advance for the help. ...Show All

• Visual Studio Team System Recreating ReportServer database

  I had posted a similar thread in the Setup & Administration forum, but never received an answer. The issue was that I had upgraded to the Beta 3 Refresh from Beta 3 running on SQL Server 2005 Standard September CTP. I attempted the upgrade to SQL Server 2005 Standard RTM, but as anyone who tried this remembers it wipes out most of your databases. Of course I had backups, but this required me to deviate slightly from the upgrade guidelines as I could not simply attach the MDF files. At any rate, when I ran through the installation successfully (used SQL Server 2005 Enterprise RTM instead) and restored the appropriate databases everything ...Show All

• .NET Development OutOfMemoryException and Garbage Collection doesn't work how I thought it would

  I designed this code snippet to test garbage collection.  It doesn't do what I thought it would do though.  The idea was to allocate a chunk of memory, but to discard the reference to that chunk by letting the variable that holds the reference fall out of scope.  When it runs out of memory on the heap, I expected the garbage collector to run automatically and that the allocation would succeed.  But there are a couple of weird things that happen.  First, here's the code: while ( true ) {     int successes = 0;     try     {       & ...Show All

• Windows Forms Dataset Changes Using Two Forms Linked to One Dataset

  I have created a simple database program using the new automation tools supplied by Visual Studio 2005 and SQLServer 2005 Developer Edition. I have created a link to a single data source containing one table. In the first form, I have used the data source tools to drag a "DataGridView" to the form , creating a BindingSource, TableAdaper, BindingNavigator and DataSource In the second form, I use the same data source to drag the same fields to the form, but with text boxes instead of a grid. I open the second form from the first form and tie the grid rows using the BindingSource.Position from the first form. The second form shows ...Show All

• Smart Device Development Handling events in a multi-form application

  I'm trying to write a .NET CF 2.0 application that behaves a little like the built-in Calendar application, in that the main form has multiple views with very different contents. In fact, in my application the four views are so different that I'd like to implement them as four different forms, so that I can use the Visual Studio designer to layout and script each one separately. This also allows me to completely close the forms I'm not using so that they're not taking up memory. Taking some inspiration from the FormStack sample code, I replaced the usual call to Application.Run() with a custom routine that does: do {     Appl ...Show All

• SQL Server Nested Loops in the Control Flow

  I have a problem when using nested loops in my Control Flow. The package contains an outer Foreach Loop using the Foreach File Enumerator which in my test case will loop over two files found in a directory. Inside this loop is another Foreach Loop using the Foreach Nodelist Enumerator. Before entering the inner loop a variable, xpath, is set to a value that depends on the current file, i e /file[name = '@CurrentFileName']/content . The Nodelist Enumerator is set to use this variable as its OuterXPATHString. Now, this is what happens: First Iteration: The first file is found and the value of xpath = /file[name = 'test1.txt']/content. When ...Show All

• SQL Server common path names

  Is there a way create a path name so that it does not have to change when testing modifications Our DTS packages have package logging, package properties/logging, pointing to a path on a network drive for production runs. E.g. \\G4\CognosDev\EmpireTime\New_Empire_Time\Admin\Logs\log file.txt I have to change the path name to point to my local disk drive when testing DTS packages locally and then change it back to the network drive when testing is complete. I'd like to use a common path name that will point to my local drive when testing and the network drive for production. Is this possible Thanks, Tom ...Show All
